Improve product aperture ratio by controlling magnitude of reverse tilt domain

Abstract

In thin-film-transistor LCD, aperture ratio is an important parameter of transmittance. In this paper, we describe the relation between aperture ratio and reverse tilt domain. We conclude that we can control the magnitude of reverse tilt domain by changing rubbing density, pile impression, cell gap and altitude of TFT. Consequently, relatively large aperture ratio could be obtained by decreasing the area of black matrix.
